When people visit our office they are often intrigued by our Green Screen studio and want to know how it works and how we create certain tricks and effects within our videos. We are not scared to give away some of the tools of the trade, so we thought it may be of interest to our viewers to gain a little bit of insight into how we work in post-production.
Let’s answer two of the questions we have been asked about our Homepage Video.
Firstly, there are two very important statements that will help you understand better the details of the answers.
One: Shooting a talent properly, against a green or blue screen screen will allow you to do almost anything in post production.
Two: There are many ways to achieving the same results.
Now that that is out of the way, let’s get onto the questions:
How does the arm (in the Creativa Homepage video) reach out of the camera frame and touch the bottom (Facebook link) on screen?
Let’s have a look at a screen shot of that part of the video.
The first thing to notice is that the arm is actually still within the camera frame. All we did was put the Creativa YouTube Channel image over the talent so that it looks like the video he is in in on our YouTube channel.
In order to get the talent’s arm to ‘pop’ out of the ‘screen’, we shot the talent in front of a green screen, then put another green screen in front of him from about waist down. So, when he is talking, both his arms and half his body is behind another green screen, much like a puppet show. Then all he needs to do is to reach out over the green screen in front of him to “touch” the button.
Of course it requires some planning for the talent to know where to touch so that his hand position matches where the button should be when added in post-production.
As mentioned before, there are other ways of doing this, but this is one of the simplest methods.
How did your arm stretch so far to grab the “FLEXIBLE” sign?
Again, let’s take a closer look at a screen shot of that part of the video.
Look at the blue circle, what do you notice?
There is no shadow on the floor. This means that our talent isn’t really standing in front of the green screen you see. In fact, he has already been ‘keyed’ (Process of removing the green background of the green screen so that you can replace it with any background) out from the green screen studio, and the background has been replaced with, in this case, a picture of a green screen studio.
This is so that it is easier to do the next part.
Now look at the red circle. You will notice that there is ‘joint’ there. So what you think is the talent’s arm is really an image of an arm created in Photoshop.
So all the talent needed to do was to hold his arm out as still as he can; and someone handed him the “FLEXIBLE” sign. In post-production, after keying out the background, we can also “cut” out his hand, ‘attach’ it to a fake arm, ‘stretch’ it out of the frame and then back, so that it looks like it grabbed the sign from out of the frame; when in reality, there was just a guy standing near the talent who handed the sign to him.
All this can be easily done because the talent was shot on green screen and anything we don’t want can easily be removed and replaced, especially the background. Again, this can be done in several other ways, but in this video, this method is the simplest way to do it.
I hope these explanations have been helpful and have given you a better understanding into the wide world of video production. Until next time!
